VENTILATOR.

Specification of Letters Patent. ]"ai-(x/nfed Spt. 2; j 913 Application led August 28, 1912. Serial No. 717,445.

o all eli/10m 'it may concern lle itknown that l, THOMAS H. GARLAND, a resident of the city of Chicago, in the county of (look and Slate of Illinois, have invented certain new and useful Improve- .inents in Ventilators, of which the 'follow- 'passageway applied over the outer end oi an opening through the car roof, and register mechanism was applied in the inner end of thel carroof opening. lfVith such an arrangement the register is in more or less horizontal position and When its vanes are closed a surface is otiered for the accumulation of dust, cinders, soot, etc., coming from the exterior of the car and particularly from passinf,r trains, and a slight leakage'through the vanes will also draw up lint, dust, etc., into the crevices between the vaiies -so that as soon as the register is opened the entire accumulation thereon falls into the car.

The main object of my invention is theretore to provide-such an arrangement that `accumulation of dust, soot, etc., will he eliminated and this I: accomplish hy setting register mechanism in vertical position sov that material thrown against the vanes will immediately drop, and l provide a sill board in front otlwhieh the material will drop. and be prevented from. entering the car. when the register is opened; A preferable arrangement is to huild the register into the ventilator as a: structu 'al part thereof, and preferably applied across the'iiiouth of the eduction passageway, a inish grating plate heineY then applied over the inner end of the outlet opening through the ear roof.-

Another object is to provide improved arraiigementsfor enabling the register varies to he readily7 adjusted from the interior of the car and 'for this purpose l provide a lever connected with the `vanes and extending; through the grating and ardistance below the ear ceiling where it can be readily .engaged and operated to effect the desired adjustment.

The various features of my invention are clearly shown on the accompanying drawiIlgS in whichl Figure 1 is a perspective view of the rclh roof of a ear showing a transverse section thereof and the application thereto of my improved form of ventilator structure;'Fig. 2 is an enlarged sectional view from pl'ahe Q-Q Fig. 1; Fig. 3 is a sectional view trein plane .fi-3 Fig. 2, and Fi 4 is a view like Fig. Il showinga modiiied ever arrangement tor controlling the register adjustment.

.is shown, tlieventilator comprises abase 5aiid a roof 6, walls 7, 8 and 9 extendih between the inner ends of the base and roo to forni a compartment l0, wall sections ll' and .12 extending between the outer ends ot' the hase and roof from the outer 'ends of the walls 8 and 9 and converging toward each other and then running in parallelism at their outer ends, these Walls together with Ythe base and roof forming the eduction passageway 13'. At the outer sides of the walls 11 and 12, L-shaped walls 14 and 15 span between the base and roof, the outer ends of these walls being parallel with the outer ends of Walls 11 and 12 and the inner ends of these L-shaped Walls dverging from the inner ends of the walls 11 and 12, there being thus formed at the opposite sides of the Walls 11 and l2 the L- shaped cowl passageways 1 6 and 17 which receive air in a direction longitudinalv with respect to the car and which ex el the air at right angles thereto, the expel edA airv deileetiiig across the outlet of the eduction passageway to create suctioirffeet. When the ear is traveling, the advance cowl passageway receives the air and is operative to create eduction effect' in the eduetio'nl passageway. Within the compartment,- `10 the' base 5 has the opening 18 which in practice registers with the outer end of the opening 19 provided through the arch roof 20 of the ar so that the cduction effect in passageway 13 may draw the air'out. of the car andefect proper ventilation thereof.

Register mechanism is usually associated with 'the ventilators 4to controlY the outlet the interior of the'car eliminated. In'order` to assure that the'detlected dust, oinders,v

when closed cinders, etc., tu: soon as the which would full into the car register. wus opened.

eliminate' such accumulation I dispose thcl register l lprefieraoly place it eduction passageway lil.' wall 2l extends across the inlet end of the eductiou passageway between the walls 'thereof and has n rectangular.opening 22 placed. rllhis register mechanism may be mechanism within the ventilator would I accumulate dust.. dirt, l tends through one of the grilleopenings and has a wing attachment 3T by means of which tht` rod nniy he turned as loyl ineansof the ordinary sr-as vnlvczuljusting rods.

v lly thus providil'rul register n'iechanisin as :1 .structural part oi l'lio ventilator, the arl rangement and construction of the device and its appliratiouarr `really siinpliied and owingto thel more 'or less vertical disposition olI the register vanos. the accumulation otI dust` rindt'rsetc., is prevented. across which the register' mechanism ll` is of any construction` that shown comprising-l :t plurality of vertical vaines or louvers 23 suitably pivoted and cross coi'inected and having an adjusting stud which` when.4

moved laterally will swing the louvers to adjust'the outlet area thereof or to .entirely close the opening 22. lVith this arrangement any dust, cinders, etc.,

are closed x'vouldstr'ilie the venes and would then drop to'the bottom of lthe passageway 13 so that the `vanes will always be clean and entrance olf dust, cinders, etc., to

etc., will not be blown into 'the car from the bottom vof the passageway 18,' the opening terminates at a distance short of the linse to leave a sillv section lin front of'which the detlected particles will lodge yto he thereby prevented from `entering the cer when .the register is opened. The adjusting stud 24 extends through a slot v26in this sill Isection and in order that adjustment of the register can be bet-ter accomplished fromA the interior of thecar.i various arrangements can bel used. As shown in `Figj, 'a Z-' shaped lever 27 is pivoted atene Bend at any suitable'. point aen-for examplqon'fthe bracket 28, one end of the lever having the sl'otQS) receiving the Stud and the other end of the lever extending a distance below th cereeiling yand terminating inthe eye 30 -tobe engaged by e suitable device so that upward movement will result in lateral shifting of the stud-end corresponding 2idjustment of theregister vanos.- In order to present :i more finished appearance, a

perforated plate 31 may. he applied across Ithef inner end of the openinglthrcugh thecar roof und the inner arm oitlever 27 extended downwardly through one of the openings in, vthis plate. This plete may also serve to support the bracket. 28 for the lever as shown in Fig.' 3, or` this `lever can be pivoted on one `of the side walls '32 adjacent ,'Another arrangement is shown in Fig. 4

the car roof opening 19 as shown in Fig.,1.

where-a vertical vrod 33 is journaled 'in' straps 34 on well 32 and carries at its upper end env` erm 35 connected vby a link 36 with the stud 24. The lower endv of the .rod ex which would i enter the passageway 1,3 when thevanes cuinulatcd particles will v he 'innncdiately posed in said outlet passageway and vdister mechanism.

lVhere ventilators are applied-al th(` sides ol' un arrh root, the vanrsarc diagonally disposed so :is to ereun'iore readily dellect incoming particlesl which alter such delicotion willfall down the inclined base of the ventilator and.onl ot' the passageway 13. .ils soon as the register is opened any zic-iy blown ontbof the passagcway lrl'to the exterior oll the cnr h v the ontllowing air. l

do not. oli course (.lesire to helimited to the i exact construction and arrangement shown and described as changes and modifications mightv he made which would still come wittlin the scope of the invention and I claimlthe following:
